Thyristor, diode modules support 1.4-3.6kV voltage ratings

IXYS Corp. has revealed that its wholly owned UK subsidiary, IXYS UK Westcode Ltd, has unleashed a range of high current isolated base dual thyristor and diode modules. The devices are based on the same 60mm die used in the firm's single device isolated base modules, added the company.

Construction of these modules is an 'all pressure contact' design with the die alloyed to a metallic disc and clamped between substantial internal copper electrodes for optimum thermal resistance to the isolated base, wherein the base plate is copper. The devices are available with eight different configurations of diode, thyristor and thyristor/diode combinations including an 'MCR' type that allows parallel mounting with a conventional MCC dual thyristor device to construct a double AC switch.

Thyristor and diode/thyristor modules are available with current ratings of 500-720A per device and voltage ratings from 1.4-3.6kV. All diode devices are rated at 1.08kA and voltages from 1.8-2.8kV. Device base plate is 180 x 71mm with a maximum module height of 84mm and weight of 3.5kg.

Typical applications include industrial drives, soft starts, welding and all types of front end rectification needs.
